Search for New Dielectron Resonances and Randall-Sundrum Gravitons at the Collider Detector at Fermilab

Understand

A search for new dielectron mass resonances using data recorded by the CDF II detector and corresponding to an integrated luminosity of 5.7/fb is presented.

• No significant excess over the expected standard model prediction is observed.
• In this dataset, an event with the highest dielectron mass ever observed (960 GeV/c^2) was recorded.
• The results are interpreted in the Randall-Sundrum (RS) model.
